Automatización del sistema de dosificación de combustible en generadores eléctricos y supervisión de las variables eléctricas de grupos electrógenos

Abstract

This thesis aims to design and implement an automated system for fuel dosing and remote monitoring of a set of electric generators, which were installed in response to the power outages that affected the country in 2024. A company (target client) faces operational problems due to manual fuel dosing, such as spills, downtime, lack of real-time variable monitoring, among others. The proposed solution integrated automation and industrial communication technologies, using a Siemens Logo V8.4 PLC with expansion modules, an HMI, pressure sensor, actuators, and a SCADA system developed in InduSoft Web Studio. The communication protocol used was Modbus TCP/IP, structured in a tree network topology, which allowed establishing robust communication between the devices. The system was validated through simulations in Factory I/O and final tests on the plant, both of the system and SCADA. The results obtained demonstrated the operational effectiveness of the designed system, allowing fuel dosing. The implemented system is scalable, complies with industrial programming standards, and lays the foundation for future integration with technologies oriented to Industry 4.0. Finally, the system is implemented, highlighting the operational efficiency for which it was designed, the improvement in the supervision of variables of interest, reduction of fluid handling, and scalability of the system, in addition to indicating ideas for future updates. Keywords: Industrial automation, remote monitoring, Fuel, SCADA, generator set.
